Lanczos method applications in lattice QCD

Numerical simulations in Lattice Quantum Chromodynamics, often have to deal with iterative solution of huge sparse linear systems of equations. Due to short recurrences or small memory requirement, Lanczos methods are some of the most proper methods for this type of problems. They can be used in different applications in LatticeQCD: numerical quadrature, matrix inversion and eigenvalues problems. In this work, we make a review and present some of the Lanczos method applications in LatticeQCD, using Boriçi Creutz fermions as chiral fermions on the lattice for simulations, implemented in FermiQCD and discuss their performance.
